Brief Description

Bandok.BW is a backdoor that allows hackers to gain remote access to the affected computer in order to carry out actions that compromise user confidentiality and impede the tasks performed on the computer.

It reduces the security level of the computer:
it changes the security settings of Internet Explorer, decreasing its security level.

It uses techniques included in its code to hide itself while it is active.

It uses several methods in order to avoid detection by antivirus companies:

It prevents scanning tools from running, such as Windows Registry Editor, FileMonitor, etc.

It terminates its own execution if it detects that a memory dump program is running, such as Procdump.

It terminates its own execution if it detects that a debugging program is active.

The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
